feature: add colors yellow, blue, white for new reporters
feature: add reporter "info"

The info reporter is more colorful, less indented than spec,
shows each "describe" with a begin/end pair (which is useful for
large lists of "it"s).
In contrast to spec it does not show skipped tests.
info reporter: change output of summary
fix: remove warning about shadowing

Addresses issue #32
chore: added cotire 1.6.1 as a submodule
fix: warning about shadowing
quickfix: removed auto_ptr in snowhouse to get rid of warnings

This should be fixed in snowhouse properly to accomodate both for older
and newer compilers. But this fix is needed to get green builds for now.
Merge pull request #29 from sbeyer/info-reporter-summary

New reporter info with another reporter summary
Adopt Cedar's SPEC_BEGIN/SPEC_END construct

Allow SPEC_BEGIN and SPEC_END to be used instead of the go_bandit() construct. This helps avoid the need to use the name of the test framework inside the tests.
Added matcher syntax

Assertions can now be written more like RSpec. For example...

5 must equal(5);
4 must_not equal(5);
5 must be_greater_than(4);
